Haxial software is notorious for making the most anti-Aqua, butt-ugly DOS-type interfaces. I would stay of away from them based on this principal, however, I needed cataloger, since DiskRecall (which is the best) is not yet available for X. So I gave it a chance. Conclusion: highly non-intuitive - no drag & drop and no standard menus, very feature limited, but it does have one thing going for it speed and long file name. Wait for DiskRecall or use DiskTracker, which is quite comparable.
